Stopping at junction brakes locked up without warning causing violent stop and would not release. Abs warning light illuminated. Vehicle could not be moved under own power and had to be towed . Brake shop had to disconnect ABS system and bleed brakes before vehicle could be moved on own power.had this happened on expressway 10 minutes earlier a serious accident would almost certainly have resulted.
